MECS Ford Probe
Certain Ford Probes have a WHITE TACH CONNECTOR
located very close to the 6-pin Self-Test connector and
bundled in the same wiring harness. This is NOT the STI
(Self Test Input) Pigtail.
Connect the pigtail to the BLACK STI connector located farther back on the wire
harness. If the tool is connected to the WHITE Tach connector, serious damage
will result and may void warranty. Refer to the illustration.
GM Historic
Prior to1996, most GM vehicles used the 12-pin Assembly Line Diagnostic Link
(ALDL) DLC. The GM ALDL cable kit includes the ALDL adapter and cigarette
lighter power cable. This adapter cable is included with the scan too. In 1994
and 1995, certain GM vehicles use the J1962 (OBD II) DLC, but are not OBD
II compliant. Refer to “Appendix A - Data Link Connectors".
Use the Battery Power cable to provide 12V to the tool.
The ALDL DLCs are usually located under
the dashboard on the driver’s side.
On Corvettes & Fieros, the DLC may be
located in the center console behind the
ashtray. Refer to vehicle service manual for
exact location. It may be in full view, or it
may be recessed behind a panel. An open-
ing in the panel should allow access to the recessed connector.
